Device for receiving and transposing of plates, in particular, glass plates

Abstract

In a device for receiving and transposing of plates (2), in particular glass plates from a substantially horizontal position or reversed, a pivot arm (6) is pivotable around a longitudinal axis (7) into two end positions, namely into a receiving position and a release position. A support frame (8) is mounted on the pivotable end of the pivot arm (6) being pivotably mounted around a horizontal axis (10). The support frame (8) is provided with suction cups (9) for receiving a plate (2) and is forcibly guided, so that it is turned around its pivot axis (10) at an angle which is smaller than 90° during the movement of pivot arm (6) from one end position into the other. The support frame (8) is rigidly connected with a guide rod (15) disposed in a vertical plane for an exact and poor wear guide, whereby the guide rod is guided longitudinally displaceable in guide bushing (16) which is supported pivotably and a horizontal axis (20) outside of the pivot radius (23) of pivot arm (6).

I claim: 
     
       1. Apparatus for receiving and transporting of plates, in particular glass plates, comprising: a pivot arm, pivotable around a horizontal axis along a pre-determined pivot radius between a first position, in which the plates are in substantially vertical position, and a second position, in which the plates are in a substantially horizontal position, the pivot arm being arranged at an angle of 45 degrees, with respect to the horizontal axis in the first and second positions and having a pivotable end; a support frame mounted to the pivotable end and being pivotable around a further horizontal axis for receiving and transporting a respective one of the plates between the first and second positions, the support frame being pivotable around the further horizontal axis at an angle smaller than 90 degrees upon pivoting of the pivot arm between the first and second positions; a guide rod rigidly connected with the support frame for accurately guiding the support frame between the first and second positions; and a guide bushing for guiding the guide rod in a longitudinal direction thereof; the guide bushing being pivotably mounted around a still further horizontal axis beyond the pivot radius of the pivot arm. 
     
     
       2. Apparatus in accordance with claim 1 wherein the guide rod is rigidly connected with the further horizontal axis of the support frame. 
     
     
       3. Apparatus in accordance with claim 1, wherein the guide rod is arranged substantially at a right angle with respect to the pivot arm in the first and second positions. 
     
     
       4. Apparatus in accordance with claim 1, wherein the pivot arm has a pivot angle in the range of 80 degrees to 100 degrees. 
     
     
       5. Apparatus in accordance with claim 1, wherein the horizontal axis of the pivot arm has a distance to the still further horizontal axis of the guide bushing, and the pivotable end of the pivot arm in the first position has a distance to the position of the pivotable end of the pivot arm in the second position which latter distance corresponds to the distance between the horizontal axis and the still further horizontal axis. 
     
     
       6. Apparatus in accordance with claim 1, and further comprising a pivot support for the guide bushing, the pivot support being lockable and displaceable parallel to the tangent on the pivot radius in the second position of the pivot arm, which tangent extends through the further horizontal axis of the support frame. 
     
     
       7. Apparatus in accordance with claim 1, and further comprising means for adjusting the angle between the guide rod and the plane of the support frame. 
     
     
       8. Apparatus in accordance with claim 1, and further comprising a second pivot arm, the pivot arms being provided at each side of the support frame and being fixedly connected with each other. 
     
     
       9. Apparatus in accordance with claim 8; and further comprising a connecting shaft for fixedly connecting the pivot arms.
